syslinux: fix isohybird overflows on 32 bit system
When call isohybrid with option '-u', it overflows on a 32 bits host. It
seeks to 512 bytes before the end of the image to install gpt header. If
the size of image is larger than LONG_MAX, it overflows fseek() and
cause error:
isohybrid: wrlinux-image-x86-64-20140505110100.iso: seek error - 8: Invalid argument
Replace fseek with fseeko to fix this issue.
